. It is among the objects of this invention to pro-j vide a refrigerating apparatus in which a cabinet is coordinated in an improved manner with a mechanical refrigerating system so that the sys: tem may be easily removed from; the cabinet.

It is a further object ofthis invention to mount a refrigerating system on a cabinet in an im; proved manner so that the system is efllcient in; operation and requires no exposed moving parts to produce efflcient cooling currentsoi air. v

7 Further objects and advantages of the present invention will be apparent ,from the following 1e: scription, reference being had tothe accompanye present invention isclearlyshown. 1
